Abstract
U ovom radu je mjerenjem vremenske promjene potencijala otvorenog strujnog kruga, primjenom polarizacijskih metoda (potenciodinamčke polarizacije i galvanostatske pulsne metode (uz paralelno mjerenje volumena vodika)) te elektrokemijske impedancijske spektroskopije ispitano ponašanje Al i Al-Ga legura (s 0.01, 0.05 0.10 i 0.20 % Ga) u NaCl otopini. Legiranjem aluminija malim količinama Ga (do 0.20 %) uklanjaju se njegovi osnovni nedostaci pri primjeni u Al-zrak baterijama, odnosno: • potencijal otvorenog strujnog kruga se značajno pomiče u negativni smjer, • smanjuje se spontana korozija na potencijalu otvorenog strujnog kruga, • sužava se pasivno područje potencijala, • smanjuje se polarizacija elektrode, • smanjuje se negativni diferencijalni efekt, • povećava se anodna učinkovitost. Legura s 0.10 % Ga ima najbolje karakteristike za izradu anoda u Al-zrak baterijama sa slanima elektrolitom.
Abstract (english)
In this work, the behavior of Al and Al-Ga alloys (with 0.01, 0.05, 0.10, and 0.20 % Ga) in NaCl solution is studied. Alloying Al with small amounts of Ga (up to 0.20 %) eliminates its basic drawbacks when used in Al-air batteries, namely: • the potential of the open circuit moves significantly in the negative direction, • the spontaneous corrosion at the open circuit is reduced, • the range of the passive potential narrows, • the polarization of the electrodes decreases • the negative differential effect is reduced • the efficiency of the anode increases. The alloy with 0.10 % Ga has the best properties for the production of anodes in Al-air batteries with saline electrolyte.
